The invention concerns a method of detecting hydrogen leakage from a power plant installation using hydrogen as fuel. A rate of supply of hydrogen to the power plant ("the supply rate") is determined. A rate of change of mass of hydrogen in the tank arrangement ("the rate of mass change") is determined. The supply rate is compared with the rate of mass change to determine whether leakage is taking place.
L'invention concerne un procédé de détection de fuite d'hydrogène à partir d'une installation de centrale électrique utilisant de l'hydrogène comme combustible. Un taux d'alimentation en hydrogène de la centrale électrique ("le taux d'alimentation") est déterminé. Un taux de changement de masse d'hydrogène dans l'agencement de réservoir ("le taux de changement de masse") est déterminé. Le taux d'alimentation est comparé au taux de changement de masse pour déterminer si une fuite a lieu.
